Polartec® Power Stretch®

How Does It Work?

Moisture and high relative humidity next to the skin cause discomfort. Polartec® Power Stretch® keeps the skin dry through three complementary mechanisms:

• The fabric is highly breathable and does not restrict the movement of moisture vapor.
• "Touch points" on the fabric inner surface draw off the sweat. Sweat is wicked off the skin to the outside of the fabric, where it spreads rapidly for evaporation.
• When the sweat reaches the outside of the fabric, it spreads out to many times its original surface area, enabling it to dry at least 2 times faster than cotton.
